When to prune flowering currant in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune flowering currant
Cut back flowered shoots by roughly one-third to a healthy outward-facing bud. Remove one or two of the oldest, most congested stems to the base each year to encourage fresh basal growth. Avoid pruning in late summer or autumn — you will remove next spring's flower buds.
Flowering currant (Ribes sanguineum) blooms on wood grown the previous season, so pruning immediately after flowering preserves next year's display. Annual post-flower pruning keeps the shrub shapely and prevents it becoming a leggy tangle. Hard renovation every few years rejuvenates old, overcrowded plants.

When should I prune flowering currant in the UK?
Prune flowering currant in early to mid spring. For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell.

Is it illegal to prune flowering currant in spring or summer in the UK?
Pruning itself is not illegal, but destroying an active nest is. Under the Wildlife and Countryside Act 1981 it is a criminal offence to damage or destroy the nest of any wild bird while it is being built or in use, and the RHS treats the nesting season as March to August, sometimes longer. Check flowering currant for nests before cutting, and if you find an active one, leave that part of the plant until the birds have fledged.

Why is UK pruning timing different from American advice?
Most pruning guides online are written for US conditions and anchored to USDA zones. Britain's maritime climate gives milder winters but later, less predictable last frosts — from March in the south-west to mid-May in the north — so the RHS advises against winter pruning for most plants: it pushes out soft growth that a late frost then kills. Britain also has the nesting-bird law, which has no US equivalent.
